blockchain is a system of recording information in a way that makes it difficult or impossible Blockchain is a shared, immutable ledger that facilitates the process of recording transactions and tracking assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding).
Central to the appeal and functionality of Bitcoin and other cryptocurrencies is blockchain technology. As its name indicates, a blockchain is essentially a set of connected blocks of information on an online ledger. Each block contains a set of transactions that have been independently verified by each validator on a network.
Every new block generated must be verified by each node before being confirmed, making it almost impossible to forge transaction histories.1 The contents of the online ledger must be agreed upon by a network of individual nodes, or computers that maintain the ledger.
Experts say that blockchain technology can serve multiple industries, supply chains, and processes such as online voting and crowdfunding. Financial institutions such as JPMorgan Chase & Co. (JPM) are testing the use of blockchain technology to lower transaction costs by streamlining payment processing.2

Blockchain is a distributed, digital ledger technology that records transactions in a secure, transparent, and tamper-resistant way. Unlike traditional databases, blockchain stores data in blocks that are chained together, making it nearly impossible to alter any single record without changing all subsequent blocks. This decentralized structure means no single entity controls the data—everyone in the network has access to the same, up-to-date information.
Each block in a blockchain contains a group of transactions, a timestamp, and a unique cryptographic hash. When new transactions occur, they are grouped into a block and verified by network participants (often called "nodes" or "miners"). Once validated, the new block is linked to the previous one, forming a chronological chain. This process ensures transparency and makes the system highly resistant to fraud and hacking attempts.
